To kick off...

I like this fetish of women stroking the penises of men and ordering them to ejaculate.  This is a great example. Clip 5 and 6 are seriously hot.  Mistresses' Autumn (bare breasts) and Monique (no panties) order these gentlemen to cum while wanking their erect penises.

I love the way Autumn says "Yes.  Cum." while expertly stroking that cock in a glass bowl.  Awesome.

In clip 10, a gentleman masturbates his cumming cock over a woman while another gentleman is having anal intercourse with him!

Two sexy, clothed girls encourage a naked male to masturbate his penis, then ejaculate over a pair of cotton panties;
